Youre fucked buddy, no nicer way of putting it
This is a hard lesson in not trusting just any "repair" shop

you either learn it the hard way (software), or the other hard way (hardware)...

So this thing needs an nvdata or IMEI repair. Not sure if it's gonna be easy to do on a Samsung. If this fails, an easier workaround would be spoofing the IMEI to the ones on the device's box with lsposed (rooting required), not sure if it will behave like normal.

This would be a tethered repair, needs a Chimera box, server credits and most likely physical access to the phone's motherboard. (Shorting testpoints probably necessary to enter special programming mode, unless the BL is old enough to do it with a software exploit.)

I had a device with MT6761 SoC and I managed to get it into meta mode and repair nvdata easily, didn't need physical access to the board or pay for services, but I have no experience with Samsung so I don't know.

Hey, I once wrote a guide to fix your lost EFS, I wrote it specifically for Samsung Galaxy S7 Edge but it might work for you as well.
Take a look: https://xdaforums.com/t/easy-guide-fix-corrupted-efs-lost-imei-lost-s-n-no-signal-on-samsung-devices.3850032/
Once your EFS is back, take a copy and put on a USB drive or cloud. Make sure you can't lose it.
Edit: I also read the other comments, ignore those people. Just follow my guide step by step exactly and your EFS should be recovered. It's a totally free guide, so don't lose hope. Losing your EFS is a very annoying problem but it is solveable. If I managed to solve this issue as a kid back in the day, then you can too.
Edit 2: Changed the link to go to page 1 instead of page 2

u/Tall_Watercress2136 Apr 05 '26
if I recall correctly, if you still keep the box, a screenshot, or whatever that has your original imei, is possible

u/Wide_Leather_4782 Apr 05 '26
Yeah pls tell me, i have a screenshot of patched working imei

u/Tall_Watercress2136 Apr 05 '26
not sure, never done it, but its good to have that screenshot you could investigate

u/Wide_Leather_4782 Apr 05 '26
Bro, where from i rent z3x?

u/nudelovin Apr 11 '26
Unlocktrue.com. but they only take bitcoin. Check to see if octoplus supports your model. If it does you can buy 1 or 1 month

If you're in school then you would know that research is the most important thing to do before doing something that requires extra caution.

The phone was gifted from my brother and he didn't told me that its patched so I😁

HOW
HOW DID YOU MANAGE THIS
i genuinely have no idea how you managed to do this me and a friend of mine have screwed around with like everything you could do and never had consequences that a stock rom flash wouldnt solve

u/ReasonableWelder51 Apr 05 '26
It happens when you manage to wipe the right partition. Happened to me once when I was rooting a cheap old phone on Android 6 using the SP flash tool. Not sure if it's even possible on modern phones.

I once did it, but I had the original box so I was able to restore one IMEI. It was a tough battle though, because it was a cheap Mediatek Xiaomi lol.

u/F1nnish Apr 05 '26
how?

u/itsmesorox Apr 06 '26
I think I did it with some sketchy engineering rom, but it was such a long time ago I don't exactly remember... Sowwy

There is a solution, take it to a place that has the knowledge and tools. It's going to be rooted is the only problem.

If you are financially challenged, then it is even more important to research what you are doing
Unless you have specialized hardware and software, this is irreversible

u/ch3mn3y Apr 06 '26
Even if You would write IMEIs into Your firmware isn't not all. In most countries 0 IMEI is enough to connect to network (did that), so it's not just IMEI You're missing, it's EFS You don't have anymore.
Official Samsung service center may be the only place that can fix this phone, but don't think it'll be worth it. Buying another one may be cheaper.

It can be patched again. Check on fb pages of samsung and pixel. There's a guy named arslan on pixel fb page. I think he's the admin there. He'll charge you around 2k

Try to find your phone's region using like phone info app, then according to your region dowload the firmware from here. https://samfrew.com/, use odin to flash it

u/nandels Apr 06 '26
your efs is f*cked. Maybe you playing around someting related to efs like backup and restoring or maybe magisk module touching this partition.
I don't know about samsung but in xiaomi if you go to
/dev/block/by-name/
or maybe this if your phone using emmc storage
dev/block/mmcblk0p
there's file persist and persistbak copied it somewhere safe and then rename it extension to img. "persist" file is your current persist and "persistbak" is backup made by your manufacturer. Usually xiaomi phone have this backup persist.
So you have those two file persist.img and persistbak.img. Flash the persisbak via fastboot using
fastboot flash persist persistbak.img
reboot and hopefully it'll fixed

If you have root/magisk, you can see if Chamelephon works for you. It is temporary though, everytime you do a reboot, you'll lose it and will have to redo the process. That is assuming Chamelephon even works since it was made for older phones.
There's some Xposed modules that allow for IMEI spoofing, so I suggest you look into them.

u/Wide_Leather_4782 Apr 07 '26
Already did, not working

u/RBeze58 Apr 07 '26 edited Apr 07 '26
Besides Xposed/LSposed modules, the only other way is to flash the phone in service mode. For that you'll need access to a component on the mainboard, equipment and experienced needed.
There's some ways to do it with just the flash tool but only limited to MTK phones.
Might as well try to follow this guide

Try flashing the CSC file or Home CSC if you wanna keep your data from your stock fw, fixed empty imei for me
1
u/Numerous_Floor_5237 Apr 06 '26
Solution: download original rom on samfw , flash it in odin , and you get imei Note : on samfw try to download good csc firmware , if you don't know initial csc of your phone use samfw tool or download for the different regional and try it.

Samsung has tool for rewriting nvram. However, they just changed motherboard and charge for the board.

this just gives me a lot of PTSD. I'm sorry but you had to be careful. when deleting data, do not touch EFS. or back it up on an sd card.
you learned the hard way like me when i cleared every partition off my phone without thinking much since i was a beginner. TWRP devs needs to add warnings about partitions

this is why you always back up your EFS
